Biomining in China: History and Current Status
Nov 15, 2022Metallurgists often used acid mine drainage (AMD) for improving the bioleaching efficiency of metal ores, without knowing how the bioleaching process worked. Since the discovery of bacteria associated with AMD in 1947 by Colmer et al. (Colmer et al. 1950 ; Temple and Colmer 1951 ), microbiologists started to search for, isolate and select

Study of acid mine drainage production potential in flotation
Jan 09, 2015The terms acid rock drainage (ARD) and acid mine drainage (AMD) refer to liquid effluents, which occur as a result of natural oxidation of sulfide minerals contained in rocks exposed to air and water (Truter et al. 2014; Gaikwad et al. 2011; Akcil and Koldas 2006).Such minerals are chemically (and biologically) stable in situations where both oxygen and water are

What can be done to prevent or clean up acid mine drainage?
Water flowing through active or abandoned mine sites can become polluted by the material being mined[1]. By far the most common mine drainage problem is that of acid mine drainage (AMD). Sulfuric acid is produced when water interacts with sulfur-bearing materials in the presence of oxygen and common bacteria[1]. The acidic water formed by this process can dissolve many

May 17, 2016The first step in the acid mine drainage flowsheet is de-carbonation. In many cases, chemical consumption is the number one operating cost of an acid mine drainage treatment system. As such, it is critical that chemical usage be optimized. Typically, with acid mine water, there is a high amount of CO 2 in the waste stream.
